Thanks guys...I did ramp the exposure for proms, but didn't see any this morning.

That said, I did not adjust the central frequency of my filter to look for any red/blue shifted features, so maybe there is something there that I simply missed.

P.S.
Just checked Big Bear's full disk image. No proms.

Indeed...just looked at the Learmonth data. Suspect they are doppler shifted a tad.
